Mallesham Dasari


Hi! I am a PhD Candidate in Computer Science at Stony Brook University. I work in WINGS Lab under the guidance of Prof. Samir Das. I also closely work with Prof. Aruna Balasubramanian. My research interests are broadly in Multimedia Systems, Mobile Computing, and Wireless Networking, with a current focus on improving the quality of experience of Internet Video applications (e.g., 360-Degree Video, AR/VR). More recently, I started exploring AI-powered Video Compression Research.


I have been working at NEC Labs, Princeton, NJ, under the guidance of Dr. Karthikeyan Sundaresan, since the summer of 2020.

Active Research Projects

AI-Powered Video Compression and Streaming

Video compression plays a central role for Internet video applications in reducing the network bandwidth requirement. Traditional algorithm-driven compression methods have served well to realize today's Internet video applications with an acceptable user experience. However, emerging 4K/8K/360-Degree video streaming, and AR/VR applications require orders of magnitude more bandwidth than today's applications. The monolithic, application-unware nature of the current generation compression algorithms is not scalable to realize such nearfuture applications over the Internet. This project explores data-driven techniques to significantly change the landscape of the source compression algorithms and improve the experience of next-generation video applications.


Multi-User Tracking for AR/VR Applications

The interactive and immersive applications such as Augmented Reality (AR) and Virtual Reality (VR) have significant potential for various tasks like industrial training, collaborative robotics, remote operation, etc. A key challenge to deliver these applications is to provide accurate and robust tracking of multiple agents (humans and robots) involved in every-day, challenging environments. Current AR/VR solutions rely on visual tracking algorithms (e.g., SLAM/Odometry) that are highly sensitive to environment (e.g., lighting conditions). This project explores augmenting the RF-positioning (e.g., WiFi/UWB) to improve the tracking in terms of accuracy, robustness, and scalability across multiple agents.
